TYPEWRITING MACHINE.

Application filed July 2,

To all whom it may concern: if

Be it known that I, BURNHAM C. STICK- Nnr, a citizen of the United States, residing at Elizabeth, in'the county of Union and State of New Jersey, have invented certain new and useful Improvements in Typewriting lvi'achines, of which the following is a specification.

This invention relates to sound-deadeninn hoods or casings for typewriting machines, and is of the same general type snown in my application, Serial No. 429,617, filed December 10, 1920, and in the application of John lValdheim, Serial No. 466,820, filed May t, 1921.

The casing comprises a body part, and a cover hinged at the rear to the body part, said body part having a large front opening thri'iugh which the machine may be in sorted into the casing, and a removable front cover plate for closing the opening after the inachinehas been inserted.

A longitudinal slot is provided at the front between the cover and the body part, through which various operating levers on the traveling typewriter carriage, such as the line-space lever, the carriage-return lever, and the carriage-release lever, may project, so that the ordinary operation of the machine may be carried on without raising; the cover of the casing. To close all of the slot not occupied by these operatinnlevers, there are provided eo-operating cushions of sound-deadening material attached to the body part and cover, respectively. When the carriagarelease lever is operated, the lower cushion will ordinarily be depressed,- and, to prevent excessive crushing of said cushion, that portion of the lower cushion overwhich the carriagerelease lever operates is floatingly mounted on the body part, so that it is depressible bodily by the lever.

Another feature of this invention is the provision of means forlransnaitting the sound of the line-end bell-signal to the outside of the casing: and forwardly toward the operator. Said means comprises a horn mounted in the side of the casing, one end of the horn opening to the outside of the casing, its other end projecting; inwardly into the bodv of the tvaewritinog machine 1921. Serial No. 482,056.

and terminating adjacent thebell, said horn being collaps ble, so that the portion thereof which pro ects into the machine may be withdrawnwvhen it is desired'to remove the machinefrom the casing. The horn opens atits outerend to the outside of the casing at one sidethereof, and, to transmit the sound forwardly, there is mounted on the side wall of the casing a deflector having one end thereof'in communication with the,

outer end of the horn, and the other end thereof extending. forwardly toward the front of the casing. The horn is mounted so'that the bell closes its inner end, thus preventing sounds other than those due to' pose, there is provided an opening in the side wall of the casing ad acent the r1bbon-.

winding mechanism, to allow access to said niechanisn'i. A pivotally mounted door may be provided, which, when opened, allows access to the ribbon-winding mechanism, but which is normally closed to prevent escape of sound through the side of the casing.

Other features and advantages will here inafter appear. f

The Underwood standard typewriting IOU carried by said type-bars, to print against these operating levers. there is provided a a plate-n 15 journaled in the end Walls 16 cushion 52 of sound-deadening material, of a platen-frame 17, forming part of the such as plush, felt or soft leather, in the usual typewvritercarriage- 18: -which is form -of-=a loopwhose =two-ply--edgesare mounted for letter-feeding movement: upon clamped between bars 53, to form a unit a front rail (not shown) and a rear rail 19 which is mounted upon the front wall 50, on the main typewriter frame. The car so that the loop 52 extends down'vmrdly to riage is provided with the usual forwardly close that portion of the slot between the and downwardly extending operating levers, front walland the operating levers. To such as the carriage release lever 21, the earclose --the portion of the slot between the riage-return finger-piece 22 and the linefront plate 42 and the levers, there is prospace handle 23.

To transmit the sound of the line-end bellsignal to the outside of the casing, so that the operator will hear the signal, there is provided a horn 70, comprising a tube '71, having its outer end passingthrough the side wall of the casing which is adjacent said bell, and a second tube 72, slidably mounted within said tube 71, by means of headed studs 73, fixed to the tube 72 and operating in slots 74 in the tube71, said inner tube 72 being movable inwardly by means of a handle 75' fixed thereto until the inner end of said tube is near thejbell 25. The handle preferably extends upwardly and operates in the space between the side of the machine and the side of the casing. The sound of the bell will thuspass through said horn to the outside of the cas- 111 audible to the operator, there is attached to the outer end of the horn, upon the outside of the casing, a deflector 7 7 having its front end opening adjacent the front of-the casing. The bell lodges in and substantially fills the inner end of tube 72, so that, while the bell-signal is transmitted to the outside, it is not possible for other noises arising in the operation of the machine to be transmitted through said horn- It will be noted that the inner end oftube 72 extends inwardly into the body of the ma-.

chine and would obstruct the machine when the latter was removed from the casing, un-

less said tube were previously withdrawn. To withdraw the tube fromthe body of the machine, prior to removing the machine from the casing, the handle is moved outwardly to cause tube 72 to telescope with in: the tube 71, the forn'iersliding within the latter by means of the screws 73 operating in slots 74 until the inner end of tube .72 is completely out of the path of the machine. Th e hell is preferably mounted upon the main frame of the machine by means of an arm proj ecting upwardly from saidiframe, said bell being fixed to said arm preferably by a screw 81, the inner tube 72 being provided with a cutout portion 82 to clear said arm 80. The horn is thus collapsible, at will, to permit the machine to be moved in or out of the casing.

The ribbon-winging mechanism 27 is positioned at one side and within themain body of the machine, so that itis contained within the body portion of the casing below the extensions 39, which would ordinarily render access thereto difficult without removing the casing. To allow access to said mechanism without removing the casing,

the-re is provided in the side wal, adjacent.

ably by a. knob 92, said and, to render said signal still more said mechanism, an opening 90, permitting through said opening90, there is provided a pivotally-mountcd door 91, which may be swung to open or closed position, preferdoor being held in closed position by a spring-catch or detent 93,thu s effectually closing the side of the casing-during the operation of the machine.

To support-the casing more firmly upon a base, the body part of the casing is provided with inturned flanges at its lower end. The machine is held firmly in position within the casing by means of abut ments 96 on the front plate 42 and the abut of the body part.

ments'tO on the rear wall The casing may. be lined with any suitable sound-deadening material to more effectively deaden the sound. r

Variations may he resorted to within the scope of the invention, and portions of the improvements may be used without others. 7
